With the rack cooling format, a closed loop is created by laterally connecting the rack to the cool unit by means of additional frames placed at the ends of the assembly enabling maximum use of the rack in depth and optimisation of the air flows.
 
When recirculating the air outside the rack, there are no obstructions or equipment to prevent the installed servers from being cooled properly, thus ensuring that the cool air reaches the front of the rack at all times, regardless of the position in which the servers are set up
 
Furthermore, since the air is not expelled outside the aisle but rather moves through the front/rear frames, greater ΔT are achieved which ensures that the units continue to work in best cooling zone.

 

The HDC-Rack is the most efficient solution, as it is possible to work with ΔT of the air up to 25°C, and is therefore the most ideal solution for ultra high-density applications combined with external Free-Cooling type chillers
 
 

Benefits:

  •  Individual cooling for 1 or 2 racks.
  •  Possibility of Redundancy N+1.
  •  Real time information and supervision at rack-level.
  •  Fast response capability and regulation of the cooling unit operation.
  •  The air flows are completely contained within the rack.
  •  Air conditioning independent of the room conditions (heat and dust).
  •  Can be implemented in rooms not configured as a Data Centre.
  •  Can be implemented in rooms whose initial layout was not intended for high-density needs.
  •  Requires little space.
  •  Low noise.
  •  Easy to install hydraulics.
  •  Possibility to adapt to any ARCTIC rack already in operation.
  •  Possibility to change over to an aisle system.
  •  Thermally neutral with the room.
Highlighted Feature :
  • capacity of up to 36 Kw with a 12°C water inlet - More Free Cooling Chance
  • air-flow over 5000m3/h, at a temperature of 22°C.
  • ready for operation with ΔT of the air of up to 25°C,
  • Automatic regulation of operation according to real time needs
  • Remote management using a SNMP / Modbus and Sophisticated Monitoring Software
